WINDOW-SASH runes.V

SPECIFICATION forming part of Letters Patent No.' 432,119, dated July 15, 1890.

Application filed February 13, 1889. Serial No. 299,799. (Model.)

To a/ZZ whom, it may concern.-

Be it known that l, GEORGE D. OROCKER, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California, have invented certain new and usef ul Improvements in Windm y-Sash Hinges, of which the following is a specification.

The object of my invention is to construct a hinge adapted to a window-sash and window-frame, whereby the sash,while being free to move up and down in the ordinary way, can also, when desired, be hinged to one side of the window-frame, so as to be swung inward horizontally,therebyproviding easy access to the outer surface of the sash and panes for the purpose of cleaning, painting, and repairing the same while the operator is standing on the floor inside of the building.

These hinges are so constructed that when the sashes are swung into the frame in their normal position certain parts of the hinges can be quickly adjusted by a single movement of the operator-s hand in such a manner that the parts of the hinges attached to the sash will slide freely past the parts attached to the window-frame when the sash is slid up and down in its grooves in the frame in the usual manner.

In the accompanying drawings, Figure l is a perspective view which represents the whole of one of these hinges when in .its engaged position ready to be swung inward, the lefthand or pintle leaf being' for attachment to a window-frame and the right-hand or socket leaf being for attachment to a window-sash. Fig. 2 is a perspective view representing the socket-leaf of one of these hinges, showing the position of the socket-bolt when pushed into its recess or shell, and is in a non-engaging position with the pintle. Fig. 3 is a erspective view representing the socket-bolt removed from its recess in the leaf, and showing an inclined slot in its lower side and a round hole in its rear end,which runs lengthwise nearly to the socket. Fig. a is a perspective view representing the same device illustrated in Fig. 3, showing a long slot in the upper side. Fig. 5 represents a sectional plan view through the center of the socketleaf and socket-bolt. Fig. 6 represents atop view of the socket-leaf with the socket-bolt projecting therefrom.

The same numerals4 of reference indicate the same or corresponding parts in all the figures.

The numeral D in Fig. 1 indicates the pintle-leaf of the hinge provided with a pintleblock 18 and lug 19, all cast in one piece, and is provided with a steel pintle 2l., which is firmly set in Vpintle-block 18. This leaf of the hinge is for attachment to a window-stop and window-frame.

rlhe numeral 8 indicates the socket-leaf of the hinge, which consists of a rearwardlyprojecting shell 10, having a recess 23 in the front, and a little below having another recess or slot 20, all cast in one piece, and is provided with a movable socket-block 7 having a socket 22, which receives pintle 2l. This leaf of Athe hinge is for attachmentto a window-sash. The projecting shell l0 is to be set into the sash.

The numeral 19 indicates a lug, which is caston the pintle-block, and 2O indicates a recess or slot in the socket-leaf of the hinge, which receives this lug when this leaf of the hinge is turned inward, thereby preventing it from lift-ing` and the socket being thrown oif of the pintle while it is swung in; but when it is swung back to its normal place it can easily be lifted oif.

The numeral 7, Fig. 2, indicates the socketbolt pushed into its recess 23,being in a nonengaging position, and is held in said position by a catch-pin 15, (shown in Fig. 5,) which is firmly set in and near to the front end of a flat spring 14, which is secured at its other end to the under side of projecting shell 10. The under side of said socket-bolt has an inclined slot 1l, as shown in Fig. 3, and when the socket-block is pushed into its recess this incline presses down the catch-pin l5, and it snaps into the lower part of socket 22, thereby holding said socket-bolt in its shell or recess. This socket-bolt is hollow, being drilled out from its rear end, as shown at 30 in Figs. 3 and 4. rlhishole extends lengthwise nearly to the socket 22, as shown in Fig. 5, and in which is seated a coiled spring 13, one end of which is bearing against the back end of recess 23, being held in position by a guide-pin 17, and when the socket-'bolt is pushed into its recess, as shown in Fig. 2, this coiled spring is pressed in and completely embedded within ICO the bolt. By reference to Fig. 1 it will be seen that this bolt has along slot 12 in its upper side, and byreferring to Fig. 5 it will be seen that the end of a rivet or screw 16 (which passes through the top ot' projecting shell 10) is loosely engaged in this slot 12, whereby t-he bolt is limited in its sliding movement, and in connection with the catch-pin 15, engaging loosely in the inclined slot 11 in the under side, the bolt is prevented from being drawn out of its recess. Now by referring to Figs. 2 and 5 it will be seen that by pressing down the end of flat spring 14 the catch-pin 15 is drawn out of the lower part of socket 22, and the boltis instantly thrown out of its recess by coiled spring 13, and the socket 22 is in an engaging position ready to receive the pintle 21.

The operation of the device is as follows: Raise the socket-leaf 8 till the socket-bolt is off of the pintle. Then by one movement of the thumb or linger push the socket-bolt into recess 23, as shown in Fig. 2. Then this leaf of the hinge (when attached to a window-sash) will slide freely past the pintle and pintleleaf of the other part of the hinge in the vertical sliding movement of the sash in the window-frame; but when it is desired the two parts ot' the hinge can be made to engage with each other by simply pressing down the end of liat spring 14, and the socket-bolt 7 is instantly thrown out by the coiled spring 13,

shown in Fig. 5, and is ready to receive the pintle, which is on the other leaf of the hinge.

Having thus described my invention,l claim as new and desire to secure by Letters Patent- 1. In a window-sash hinge, a hinge-leaf provided with a stationarypintle-block and pintle adapted to be attached to awindowframe, in combination with another hingeleaf provided with a slot and recess in its front face and a rearwardly-projecting shell or case, said hinge-leaf being adapted to be secured to a window-sash, a hollow sliding socket-bolt mounted in said shell and provided with a pintle-socket near its outer end, a long slot in its upper side and an inclined slot in its under side, a coiled spring seated inside of the bolt with one end of the spring pressing against the inner end of the hole in the bolt and the other end pressing against the inner closed end of the shell, whereby the bolt is projected, said latter end of the 'coiled spring being held in position by a guide pin or screw secured in the rear end of the shell, a stop-screw or rivet passing through the top of the shell and adapted to engage loosely in the long slot in the top of the bolt, whereby the projection of the bolt is limited. and a catch-spring provided with a catch-pin passing through an aperture in the under side of the shell adjacent to the face of the hinge-leaf and adapted to slide in the inclined slot in the under side of the bolt and engage in the pintle-socket of the bolt to hold the socket-bolt within its shell in -a non-engaging position with the pintle, substantially as and for the purpose speciiied.

2. In a window-sash hinge, the combination, with one of its leaves provided with a rearwardly-projecting shell and having a recess and slot in its front face, a hollow socketbolt movably seated in said recess and shell, and a coiled spring seated in said bolt and shell, adapted to project said bolt, ot a ilat spring provided with a catch-pin near its front end and secured at its other end to the rear end of the shell on its under side, said catch-pin projecting through an aperture near they front end of the shell and being adapted to engage the pintle-socket of the bolt and retain it in its shell, and the front end of the fiat spring projecting through the I slotin the front face of the hinge-leaf, thereby providing a thumb-catch to operate the catch-pin and release the socket-bolt when pushed into its shell, substantially as and for the purpose specified.

In testimony whereof I alx my' signature in presence of two witnesses.
